    Adoption of Soil Conservation through Collective Actions in SouthWestern Uganda
    (African Crop Science Journal, 2017) Kalibwani, R.M.; Kakuru, M.; Kamugisha, R.; Twebaze, J.; Tumuheirwe, H.; Tenywa, M.M.; Nyamwaro, S.O.; Mugabo, J.; Buruchara, R.
    In developing countries, access to and use of renewable natural resources are essential for rural livelihoods to thrive. Hence, cooperation in the management of natural resources is increasingly an important strategy that can enhance long-term socio-ecological resilience. In most cases, collective actions have widely been recognised as an alternative institutional arrangement to centralised governance for the management of natural resources, but their success largely depends on factors that are specific to localities where they are implemented. In this study, factors that influence adoption and extent of adoption of natural resource conservation activities were identified using two case studies: Bubaare and Bufundi Innovation Platforms in Uganda. The drivers of adoption of community natural resource management strategies are analysed using an Ordered Logit Model while extent of adoption is analysed using a truncated regression model. The education level of a household head, membership in collective action group, and perception of plot slope and relevance of bye-laws were factors associated with likelihood of adoption. Value of livestock, membership in collective action group, access to credit and off-farm income were found to positively influence the level of investment. Thus, collective action increases opportunities for adoption; hence farmers should be supported to work collectively.

    Land-use and land cover, sediment and nutrient hotspot areas changes in Lake Tanganyika Basin
    (African Journal of Rural Development (AFJRD), 2016) Azanga, E.; Majaliwa M.; Kansiime, F.; Mushagalusa, N.; Karume, K.; Tenywa, M.M.
    The impact of global land use and land cover changes in relation to climate change and declining biodiversity has been a subject of interest in the recent years. Nonetheless, there is limited data capturing trends in land use and land cover changes in the Tanganyika catchment. This study characterized the trend in land use/ cover changes and examined the change in sediment and nutrients hotspot areas in the Kalimabenge microcatchment, for the last 40 years. Land use/cover change was quantified and reconstructed by analyzing a series of Landsat images taken in 1973, 1986, and 2010 using the Integrated Land and Water Information System (ILWIS) 3.3 software and field observations. Both supervised and non-supervised classifications were used in the classification of the Landsat images in order to obtain the land use/cover change map. Sediment and nutrient loading into the Kalimabenge micro-catchment were modeled using ArcSWAT software integrated in ArcGIS 9.3. ArcSWAT was calibrated using two years field observations at the river outlet into Lake Tanganyika. Results showed that the dominant land use/covers in the micro-catchment are cultivated land, followed by forest/tree plantations, grassland and built-up area. Grassland/savannah has declined gradually over time, forest/woodlot land increased gradually, built up areas acreage remained quasi similar, cultivated land followed a quadratic trend. The partial sources of sediments, runoff and phosphorous changed for the last 4 decades. These sources areas first decreased in 1986 and then increased in 2010. Details

    Variability Of Soil Organic Carbon Stocks Under Different Land Uses: A Study In An Afro-Montane Landscape In Southwestern Uganda
    (Geoderma, 2013) Twongyirwe, R.; Sheil, D.; Majaliwa, J.G.M.; Ebanyat, P.; Tenywa, M.M.; Kumar, L.
    We explore and compare quantities and patterns of Soil Organic Carbon (SOC) in protected forest and neighboring land around Bwindi Impenetrable National Park (a mountain protected area in Southwestern Uganda). We assessed paired sites of natural forest and major land uses (potato, tea and grazing lands) converted between 1973 and 2010. These pairings were replicated at three altitudinal zones. Plots (20m by 50m) were demarcated within each site. Five composite soil and core samples were obtained from 0 to 15cm (top-soil) and 15–30cm (sub-soil) at each plot. In total, 192 composite soil and core samples were collected. Within forest we found marked site to site variation in SOC from 54.6 to 82.6Mg/ha. There was a tendency for higher SOC in converted land, associated with higher bulk density suggesting quality based land use selection with forest left on inferior soils. Cultivation, landscape position, slope and sampling depth were all significantly (P<0.05) related to variation in SOC stocks following forest conversion but time since conversion had no detectable impact. Interestingly, there was no significant relationship between SOC in the top and sub-soils. Higher SOC is largely determined by higher bulk density. The large SOC stocks in these afro-montane soils are less predictable and more persistent than anticipated.

    Women’s Vulnerability in Bean Value Chain Development at the Maendeleo Innovation Platform, Eastern DRC
    (African Journal of Rural Development, 2018) Kalibwani, R.M.; Nyamwaro, S.O.; Wimba, B.; Kakuru, M.; Tenywa, M.M.; Mugabo, J.; Buruchara, R.A.
    Value chain development in post conflict countries should not only deal with the technical issues of the value chain, but with women’s gender needs, and even more critically understand and address their vulnerabilities. The aim of this study was to investigate the vulnerabilities of women involved in a bean value chain development intervention at the Maendeloe Innovation Platform in Eastern DRC. Specifically, the paper first discusses the roles of women and men in the value chain, what production resources and benefits they access and control, the role of the IP as a vehicle for women’s empowerment, and identifies women’s gender needs. Secondly, the paper identifies women’s vulnerabilities, and the capacities that the IP could build on, to support their participation in bean value chain development. Using gender analysis tools, the study shows that in addition to the lack of control of productive resources, household assets and the benefits of their labour, women have been traumatized by the rampant sexual violation and gender-based violence in the region. The innovation platform should consider including legal, mental health and psychosocial counselling service providers as stakeholders in its activities to develop the bean value chain.
